This has just started happening last week. Doesn't matter what browser i'm running.  I've tried multiple computers, clearing browser cache etc. I also rebooted the server and it didn't fix it. It's probably just cosmetic but i'm just wondering what I should do to fix it.

Its a by-product of how dockerMan works.  For some reason, instead of merely passing the URL of the icon to the browser to display, dockerMan insists on actually downloading the icon.  The download is time-limited however, so if there's any internet slowdowns then what you're seeing is what happens.

 

You can try doing Check For Updates a couple of times and see if that makes a difference or deleting the images from config/plugins/dockerMan/images and clear your browser cache to try and fix it up.

 

But, it is a purely cosmetic issue, and the reasoning for actually downloading the images instead of passing the URL's to the browser to let it do what it is designed for has never been adequately explained.

Thanks squid. I'm glad it's nothing to really worry about
